Troubleshooting
if your BDs system isn’t performing the way you think it should, check to see if the problem is
covered in this section before calling your dealer or contacting a harman kardon representative.
Problem
Solution
the receiver won’t power up (the power indicator is not lit):
• check that the receiver’s power cord is properly plugged into the receiver’s ac
power input connector.
• check that the power cord is plugged into a working ac outlet. if the outlet is
controlled by a switch, make sure the switch is set in the “on” position.
• check that the receiver’s Main power switch (located on the rear panel) is in the
“on” position.
sound plays through the BDs system speakers, but there is no tV picture:
• check the HDMi connection between the receiver and the tV.
• check that the tV is turned on and is set to the proper input source.
• Unplug the HDMi cable from the tV and plug it back in again.
there is no sound coming from just the subwoofer:
• check that the subwoofer’s power cord is plugged into a working ac outlet.
• check that the subwoofer’s power switch is in the “on” position.
• check that the subwoofer Level control is not turned all the way down (fully
counterclockwise).
• check that the audio connection between the receiver and the subwoofer has been
properly made.
• check the receiver’s Settings: Configuration menu to make sure that the subwoofer
volume has not been set at –10dB.
there is a constant hum in the sound:
• check that all input cables are plugged all the way into their connectors.
• check that all cables are at least 10 ft (3.3m) from fluorescent lights.
• check that all cable connectors are clean. if necessary, wipe them with a cloth
slightly moistened with alcohol.
• set the subwoofer’s power switch to “off.” if the hum goes away, there is a ground
loop between the subwoofer and the receiver. plugging the subwoofer’s power cord
into the same ac outlet that the receiver is plugged into should eliminate the ground
loop.
the disc does not play:
• check that the disc is inserted correctly (label side up).
• check that the disc is the correct type: BD-Video (single-layer or double-layer),
DVD-Video, DVD+r/+rw, DVD-r/-rw, cDDa (cD digital audio), cD-r/rw. other
disc types will not play.
• check that the disc surface is clean and not scratched.

or DVD:
or DVD:
• check that the disc surface is clean and not scratched.
the sound and picture are out of sync when listening to an aux source:
• press the options button and perform the Lip sync adjustment to bring the sound
and picture into synchronization.
cannot tune in radio stations:
• check that the fM antenna is correctly connected.
• adjust the antenna’s position. if necessary, use a powered fM antenna or an
outdoor fM antenna.
the receiver does not respond to remote-control commands:
• replace all three remote-control batteries with fresh ones, and make sure that they
are installed with the correct polarity.
• Hold the remote closer to the receiver.
• check that the receiver’s remote sensor is in the line of sight of the remote control.
the remote does not control programmed components (tV or video):
• check that you have pressed the remote’s aux button before trying to operate the
component.
• re-program and/or re-teach the component’s commands into the remote.
the Ø symbol appears on the screen when you press a remote-control button:
• the selected function is not permitted at the time the button is pressed.
the receiver does not respond to commands, or it behaves in an erratic way:
• Unplug the receiver’s power cord from the ac outlet, wait 30 seconds, then plug
it back in.
